给开源项目贡献代码-摩杜云开发者社区

如何给开源项目贡献自己的代码？这里以一次真实的给阿里巴巴的分布式事务框架seata提PR为例。

1.自己的项目拉取到本地

首先fork目标项目，这里是阿里的seata,fork到自己的仓库后，将项目拉取到本地。

$ git clone git@github.com:lightClouds917/seata.git
Cloning into 'seata'...
remote: Enumerating objects: 55, done.
remote: Counting objects: 100% (55/55), done.
remote: Compressing objects: 100% (37/37), done.
remote: Total 14692 (delta 12), reused 30 (delta 4), pack-reused 14637
Receiving objects: 100% (14692/14692), 2.65 MiB | 1.52 MiB/s, done.
Resolving deltas: 100% (6070/6070), done.
Checking connectivity... done.
Checking out files: 100% (960/960), done.

这里需要注意，设置自己的账号和邮箱！

git config user.name "IT云清"
git config user.email "118xxxxxx@qq.com"

2.关联上游项目

这里的upstream，名称自己定义，为了通俗易懂，建议也以此命名。

G:\mylearn\seata>git remote add upstream git@github.com:seata/seata.git

G:\mylearn\seata>git remote -v
//本地地址
origin  git@github.com:lightClouds917/seata.git (fetch)
origin  git@github.com:lightClouds917/seata.git (push)
//上游地址
upstream        git@github.com:seata/seata.git (fetch)
upstream        git@github.com:seata/seata.git (push)

(移除上游分支命令：git remote rm upstream)

3.同步上游代码

防止你操作的过程中，上游有人提交变更了代码，我们再次同步下上游最新的代码。

G:\mylearn\seata>git branch
* develop

G:\mylearn\seata>git pull upstream develop
From github.com:seata/seata
 * branch            develop    -> FETCH_HEAD
 * [new branch]      develop    -> upstream/develop
Already up-to-date.

4.提交本地修改

本地代码修改后，就该提交了。

G:\mylearn\seata>git add .

G:\mylearn\seata>git status
On branch develop
Your branch is up-to-date with 'origin/develop'.
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)
